Abstract 25: Abnormalities within Normal Sinus Rhythm
Circulation: Cardiovascular Quality and Outcomes, 2019Trained cardiologists detect atrial fibrillation by visual interpretation of certain segments of electrocardiogram (EKG) lines known as the QRS complex. Similarly, available EKG-software also evaluates anomalies in the signals from the EKG-leads that produce the traces/lines in order to flag for atrial fibrillation.

Journal of Cardiovascular Medicine, 2011
The electrocardiographic manifestations of hyperkalemia have been well described. We report the case of a patient with permanent atrial fibrillation for 13 months, who converted to normal sinus rhythm after treatment for hyperkalemia. This is the first case of hyperkalemia-induced conversion of permanent atrial fibrillation to sinus rhythm with a well ...

Turbulence analogy in normal sinus rhythm of healthy humans
Computers in Cardiology 2000. Vol.27 (Cat. 00CH37163), 2002The complex dynamics of the autonomic nervous system manifests in the random fluctuation of the sinus rhythm. Recent results on multiple scaling and multifractal in HRV indicate intricate details beyond the second order statistics (such as the power spectrum) of the interbeat interval data (RRi).

A child with cardiogenic shock and supraventricular tachycardia presenting in normal sinus rhythm
Pediatric Emergency Care, 1996We report a case of an infant who presented in profound cardiovascular collapse with a normal sinus rhythm initially. A diagnosis of supraventricular tachycardia (SVT) was established only after hemodynamic stabilization. The possibility of SVT being masked because of severe metabolic derangements and/or painful therapeutic procedures should be kept in

To Be or Not To Be in Normal Sinus Rhythm: What Do We Really Know?
Annals of Internal Medicine, 2004Two papers in this issue raise questions about managing atrial fibrillation: Does rhythm control have any role in treating patients similar to the Atrial Fibrillation Follow-up Investigation of Rhy...

Hemodynamics before and after conversion of atrial fibrillation to normal sinus rhythm in horses.
Journal of the American Veterinary Medical Association, 1984Hemodynamic measurements were obtained from 17 horses with atrial fibrillation or flutter. Eight horses had atrial fibrillation of unknown duration. In 7 horses, atrial fibrillation developed during anesthesia.

This brief report describes several cases of paroxysmal supraventricular tachycardia that converted promptly to normal sinus rhythm within 1 to 2 minutes of receiving intravenous calcium salts as pretreatment in anticipation of verapamil therapy.

Correlates of spontaneous echo contrast in patients with mitral stenosis and normal sinus rhythm
American Heart Journal, 1994The purpose of this study was to evaluate the correlates of spontaneous echo contrast in mitral stenosis and normal sinus rhythm. Spontaneous echo contrast is associated with clot formation and embolic phenomena. It has been noted in conditions involving blood stasis, especially mitral stenosis and atrial fibrillation, but the correlates of spontaneous

[Supraventricular paroxysmal tachycardias with normal electrocardiogram in sinus rhythm].
Archivos del Instituto de Cardiologia de Mexico, 1984Paroxysmal supraventricular tachycardia (SVT) was studied in 46 patients with normal electrocardiogram (ECG) during sinus rhythm (SR), All of them had had at least one SVT crisis. They all complained of palpitations starting and ending abruptly, and of more than one hour duration.

Digitalis: Is It Useful in Congestive Heart Failure in Patients in Normal Sinus Rhythm?
Cardiology, 2008The value of digoxin in the patient in normal sinus rhythm with chronic congestive heart failure continues to be controversial. Although many patients taking digoxin have no clinical deterioration after its discontinuance, there is a subgroup of patients (up to 30% of the total group) who demonstrate clinical deterioration on digoxin withdrawal ...
